IMPROVEMENT IN APPLIANCES FOR ROLLING-MILLS.

Specification forming part of Letters Patent No. 183,888. dated October31, 1876; application filed June 24, 1876.

To all whom it may concern:

Be it known that I, JAMES F. BLACK, of Oshkosh, in the county ofWinnebago and State of Wisconsin, have invented certain new andusefullmprovement'sin Rolling-Mill Tenders and I do hereby declare thatthe followin g is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it appertains. to makeand use the same, reference being had to the accompanying drawings, andto letters of reference marked thereon, which form a part of thisspecification, and in which- Figure l is a front elevation, Fig. 2 is atop plan, Fig. 3 is a side elevation, and Fig 4 is a bottom plan, of thecarriage.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention-relates to that class of machines known as tenders torolling-mills;

and it consists in a new and useful construction and combination ofparts, whereby two men, stationed one on each side of the machine, areenabled to handle and manipulate the bar before and during the processof rolling, in the manner and for the purpose substantially ashereinafter more fully set forth.

A A are the rolls, whichare operated in the usual manner, and'may be ofany suitable construction. Embedded in or aflixed to the floor B, infront of the rolls, and parallel thereto and to each other, aretwocorrugated rails or ratchets, O 0, between which are the depressions orpits D D. E is the carriage, which consists of a stout platform orframe, composed of two or more beams, E E, united by cross-timbers E Eso as to leave a central open space, denoted by F. To the under side ofthe cross-timbers E E are affixed bearings e, carrying the shafts GG, tothe ends of which are affixed pinion-whee1s H,cut so as to fit into theratchets of the corrugated rails or depressions G O. Shafts G Gterminatein bails g for the insertion of levers or crow-bars, by meansof which the shafts are turned when it is desired to move the carriagein either direction. I is a beam bolted to the under side ofcross-pieces E E and slotted at a a in such a manner as to form twoopenings or guides for the vertical sliding ratchets K K. To the top ofratchets K K is rigidly secured the table L, which may be raised orlowered by operating the shaft M, which isjournaled in the cross-piecesE E and is provided with pinions b b, that engage with the ratchets KK.Shafts M has a bail, m, by which it may be turned by inserting acrow-bar or hand-lever. Affixed to the front end of table L are bearingsc for a short shaft, 01, that carries a pinion, f, which engages withthe horizontallysliding ratchet-rail N, upon which is rigidly securedthe box 0 for the reception and handling of the iron. Box 0 may be movedforward or backward by operating the shaft d, by its bail d, with ahand'lever, in the same manner as the other shafts herein described. Thetable L, with its superincumbent weight, is kept in the position towhich it may be raised, relative to the rolls, by spring-clamps it, thatare secured at their lower ends to uprights '5, that are mortised into,or otherwise secured to, one of the timbers E or E of the platform E.The tension of the spring-clamps it causes them to abut against the sideof table L in such a manner that when this table,

in traveling upward,reaches the eyes or bends k in the clamps h, thesewill slip in sidewise, under the table L, as shown in Fig. 1 of thedrawing, and prevent it from falling down by its own weight after theoperators let go of their levers by which they handle the liftshaft M.The spring-clamps It may be released, when it is desired to change theelevation of table L, by turning a shaft, 1, pivoted in the uprights i,and upon which are secured chains 11., whose other ends are affixed tothe springclamps h, so that by turning shaft 1, the chains n are woundaround it and the clamps pulled back, thereby releasing their hold uponthe table L, which will either sink by its own gravity, or may be raisedup higher, to reach the series of rolls next above, by operating theshaft M. The uprights i are recessed so as to afford room for the eyesIt when the clamps are pulled back by chains n, preparatory to releasingthe table L. Sometimes it may be desirable to arrange these retainingspringclamps on both sides of the table, instead of on one side only, asshown in the drawing, all the clamps being operated simultaneously by asystem of chains, in combination with the shaft or roller l, in a mannerwell understood; and it is also obvious that the number of eyes or bendsin the spring-clamps h may be varied, (only one being shown in thedrawing,) so as to retain the table at any desired elevation, accordingto the arrangement of the rolls, without departing from the spirit of myinvention.

From the foregoing description, the operation of my improvedrolling-mill tender will be readily understood. The bar or bars of ironto be subjected to the process of rolling are placed in the box 0,which, with the carriage E, is then moved opposite to, the pair of rollsit is desired to use, by operating the shafts with bars or levers, asdescribed. The carriage may be moved to either side by operating shaftsG G, and the tableL may be raised or lowered by operating shaft M, sothat the bar may be readily placed opposite to any one pair of rolls inthe entire set. When the proper place has been reached, the table L andbox 0 are kept firmly in the position, during the process of rolling thebar, by the springclamps h, in the manner described, the bar bein gcarried into the rolls by operating the shaft d.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States The tender or carriageforrolling-mills herein described, consisting of frame or platform E,shafts G G, having ratchet-wheels H, shaft M, having pinions b b,vertical sliding racks K K, table L, horizontally-sliding rack N,carrying-box O, shaft 01, having pinion f, and retraining-clamps h, thewhole constructed, combined, and operating substantially as and for thepurpose hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
